How to use

Before and After:

// Before
if (viewA != null
    && adapter != null
    && adapter.getItem(0) != null
    && callback != null
    && ...) {
    ...
}

// After
if (ObjectUtil.isNull(viewA,
                    adapter,
                    adapter.getItem(0),
                    callback,
                    ...)) {
  ....
}


String a = "a";
Object obj = null;

// Before
Log.d("MainActivity",
      "A -> " + (a != null ? a.toString() : "null") + "\n"
      + "obj -> " + (obj != null ? obj.toString() : "null")
);

// After
Log.d("MainActivity", ObjectUtil.toString(a, obj, null));


// Check empty
String b = "a";
String c = "";
String d = null;
Log.d("MainActivity", "Have string emptry ? " + ObjectUtil.isEmpty(a, c, d));


// Not Null
public void setPresenter(MainPresenter pPresenter) {
    mPresenter = ObjectUtil.requireNonNull(pPresenter,"MainPresenter is NULL");
}
